The E-TEN M600+, an upgrade of the original M600, brings with it some useful improvements: "more memory, higher resolution camera and improved Bluetooth."
TechDigest spent a bit of time with the M600 and posted their reactions to this next-generation UIQ phone. One important point? It's better than the Blackberry 7100 and supports multiple push-email solutions, including RIMs. That means this thing is patent-proof, accepting email from multiple server types.
